Why don't we just block off the exhaust pipe to prevent CO2

In summary, the conversation discusses the idea of reducing emissions by putting a cap on exhaust pipes. It also explores the amount of carbon dioxide emitted during different activities, such as jogging, and the idea of banning jogging as a solution to reducing emissions.

If you were to put a cap on your exhaust pipe your emissions will reduce thus you would solve the whole paranoia of climate shenanigans.

You could accomplish the same by holding your breath for a realllly long time.

When purchasing a new car these days we are informed that it pumps out 150g of carbon dioxide per mile travelled.

The vital capacity of adult male lungs is about 4.6 litres.

Say 40 breaths per every minute while jogging give total "exhaust" 184 litres per minute.
I doubt vital capacity could be maintained for a mile so let's call this 150 litres per minute.5% of this 150 litres per minute exhalation is CO2, i.e. 7.5 liters of CO2 per minute while jogging.

Jogging speed is approximately 6 miles per hour, (a mile in 10 minutes), => 75 litres of CO2 per mile.

That's about 3.3 moles of CO2 which is 147 grams.

So the CO2 emission of an adult male jogger is approximately 150 grams per mile.Carbon Dioxide Emission per Person (m3/h) cu metres/hour

Sleep 0.013

Resting or low activity work 0.02

Normal work 0.08 - 0.13

Hard work 0.33 - 0.38

Ergo - let us ban Jogging

1. Why is blocking off the exhaust pipe not a feasible solution for reducing CO2 emissions?

While blocking off the exhaust pipe may seem like a simple solution to reduce CO2 emissions, it is not practical for several reasons. Firstly, it would prevent the engine from functioning properly and could lead to engine damage or failure. Additionally, vehicles and other machines emit CO2 from multiple sources, not just the exhaust pipe. Blocking off the exhaust pipe would not address these other sources, such as leaks in the fuel system or evaporation from the fuel tank.

2. Can blocking off the exhaust pipe completely eliminate CO2 emissions?

No, blocking off the exhaust pipe would not completely eliminate CO2 emissions. This is because CO2 is produced not only by vehicles and machines, but also from natural sources such as plant respiration and volcanic activity. Additionally, blocking off the exhaust pipe would not address other greenhouse gases like methane and nitrous oxide, which also contribute to climate change.

3. Would blocking off the exhaust pipe be safe for the environment?

No, blocking off the exhaust pipe would not be safe for the environment. CO2 is a necessary component of the Earth's atmosphere and blocking off the exhaust pipe would disrupt the balance of gases, potentially causing harm to plants and animals. Furthermore, blocking off the exhaust pipe could lead to the release of other harmful pollutants into the environment.

4. Is there a better alternative to blocking off the exhaust pipe for reducing CO2 emissions?

Yes, there are more effective and sustainable solutions for reducing CO2 emissions. These include using renewable energy sources, improving fuel efficiency, and implementing carbon capture and storage technologies. Additionally, reducing overall energy consumption and promoting sustainable transportation options can also help decrease CO2 emissions.

5. Would blocking off the exhaust pipe have any negative impacts on the economy?

Yes, blocking off the exhaust pipe could have negative impacts on the economy. Many industries and businesses rely on vehicles and machines that emit CO2, and blocking off the exhaust pipe would significantly hinder their operations. It could also lead to job losses and increased costs for consumers. Therefore, it is important to consider the economic implications of any solution for reducing CO2 emissions.
